基于分层模型的变电站间隔资源优化方法

针对城市中心配电网中日益增多的接入需求与有限的变电站间隔资源之间所形成的矛盾,提出了一种基于分层模型的间隔资源优化方法。外层规划以变电站容量利用率均衡为目标对负荷归属的变电站进行优选;内层规划以空闲间隔数量最多为目标对负荷与各间隔的关联关系进行决策,并以变电站间隔资源利用率最大的优化方案作为最终的间隔资源配置方案。实际算例仿真结果表明,该方法具有较好的工程实用性,可为城市配电网的规划和建设工作提供参考和借鉴。

Optimization of the Bay Resources in Substations based on Hierarchical Model

With respect to the contradiction between increasing access requirements of distribution network in urban centers and the limited bay resources in power grid, a bay resource optimization method is proposed in this paper based on hierarchical model. For outer-layer planning, the substation of loads is selected for optimization by taking the balance of the substation capacity utilization as target; For inner-layer planning, the association between load and bays is taken for decision-making by taking the largest number of idle bays as target; and the maximum bay resource utilization is used as optimal scheme for final bay resource allocation scheme. The practical simulation results show that the proposed method has good practicability, and can provide a reference for the planning and construction of urban distribution networks.
